# viewDidLoad()

Called after the view controller’s view has been loaded into memory.

## Declaration

```swift
func viewDidLoad()
```

## Discussion

Discussion You can override this method to perform tasks to immediately follow the setting of the view property. Typically, your override would perform one-time instantiation and initialization of the contents of the view controller’s view. If you override this method, call this method on super at some point in your implementation in case a superclass also overrides this method. For a view controller originating in a nib file, this method is called immediately after the view property is set. For a view controller created programmatically, this method is called immediately after the loadView() method completes. The default implementation of this method does nothing.
